Описание (английский):

This document specifies requirements and test methods to assess the thermomechanical compatibility between a veneering ceramic and a metallic or ceramic substructure material used for dental restorations. This document applies only to the materials used in combination. Conformity cannot be claimed for a single material. For requirements for ceramic materials, see ISO 6872. For requirements for metallic materials see ISO 22674.

Overview

EN ISO 9693:2026 - Dentistry: Compatibility Testing for Metal-Ceramic and Ceramic-Ceramic Systems establishes internationally recognized requirements and test methods for evaluating the thermomechanical compatibility of combined materials used in dental restorations. Developed by CEN and aligned with ISO standards, this document is vital for dental professionals, material manufacturers, and testing laboratories committed to ensuring the safety, reliability, and quality of prosthodontic materials.

Focusing exclusively on the material combinations – not on individual ceramics or metals – EN ISO 9693:2026 provides a framework for testing whether veneering ceramics and their corresponding metallic or ceramic substructure materials function cohesively under the mechanical and thermal stresses found in the oral environment. This is essential for the long-term performance and patient satisfaction in dental restorative applications.

Key Topics

Thermomechanical Compatibility: The standard details how to assess the combined behavior of a veneering ceramic with its substructure material when subjected to mechanical forces and temperature variations typical in the mouth.

Requirements for Testing:

Biocompatibility: Guidance is provided on referencing ISO 10993-1 and ISO 7405 for biological risk assessments, ensuring that tested combinations do not compromise patient health.
Physical Properties: Outlines methodologies for testing thermal expansion, de-bonding/crack-initiation strength, and thermal shock resistance.
Debonding/Crack-Initiation Test: Specifies performance thresholds for material combinations (≥25 MPa for metal-ceramic and ≥20 MPa for zirconia-ceramic systems) to minimize the risk of failure.
Thermal Shock Resistance: Instructs on appropriate thermocycling tests to simulate real-world temperature fluctuations.

Sampling and Test Specimen Preparation: Guidance is provided for preparing specimens using materials from the same production lot to ensure test reliability.

Applications

Dental Material Manufacturers: Helps ensure new products are rigorously tested for compatibility before market release, meeting essential regulatory and performance standards.

Dental Laboratories: Supports the selection of appropriate material combinations for crowns, bridges, and fixed partial dentures, minimizing risks of debonding or cracking and improving the longevity of restorations.

Quality Assurance and Regulatory Compliance: Provides laboratories and manufacturers with robust testing protocols necessary for certification, market authorization, and continued product improvement.

Clinical Dentistry: Assists clinicians in understanding material behaviors, enabling more informed choices and communication with dental technicians regarding restorative options.

Research & Development: Serves as a scientific basis for comparing and optimizing new dental ceramic and metal formulations or combinations.
